These legacy charging systems produce minimal current at engine idle speeds, often dropping system voltage below 12.6V under baseline electrical loads. Operating with modern halogen headlights, electric cooling fans, or high-draw ignition upgrades quickly overwhelms the stock rectifier diodes, resulting in persistent battery drain, heat-induced diode plate failure, dim instrumentation, and intermittent ignition coil misfires under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded 95-amp unit engineered for the \u003cstrong\u003eGHN5\u003c\/strong\u003e, \u003cstrong\u003eGAN5\u003c\/strong\u003e, and \u003cstrong\u003eGAN6\u003c\/strong\u003e platforms delivers more than double the amperage of the original Lucas equipment while maintaining an authentic exterior profile. Fabricated with heavy-gauge high-temperature copper stator windings and an internally balanced high-speed rotor, this alternator ensures uninterrupted 13.5V to 14.5V output even at hot idle. Premium sealed rotor bearings prevent radial play and belt deflection issues, while a heavy-duty internal solid-state voltage regulator protects your electrical harness from damaging voltage spikes. Designed as a true bolt-on unit, it preserves OE mounting ear spacing, pulley offset, and Lucas-style 3-pin connector orientation for seamless harness integration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output 95-Amp Alternator (Part Number \u003cstrong\u003e14029\u003c\/strong\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1974-1979 MG MGB, Midget\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eBMC A-Series (1.3L), Standard SC 1500 (1.5L), BMC 18V B-Series (1.8L) \/ GHN5, GAN5, GAN6\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e50-82 hp \/ 67-92 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e14029, 14028, AL298X, AL297X, 23590, 23620, 23643, 23713, 23715, 23716, LRA00100, LRA00106\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1974 MG MGB 1.8L (BMC B-Series 18V)\u003c\/li\u003e\n  \u003cli\u003e1974 MG Midget 1.3L (BMC A-Series 1275cc)\u003c\/li\u003e\n  \u003cli\u003e1975-1979 MG Midget 1.5L (Triumph Standard SC 1493cc)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GHN5 and GAN5\/GAN6 MG MGB and Midget?\u003c\/h4\u003e\n\u003cp\u003eYes, this unit directly fits the 1974-1979 MG MGB and Midget equipped with the \u003cstrong\u003e1.3L A-Series\u003c\/strong\u003e, \u003cstrong\u003e1.5L Standard SC\u003c\/strong\u003e, and \u003cstrong\u003e1.8L 18V B-Series\u003c\/strong\u003e engines using the stock Lucas bracket layout.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my main battery charge wire with this 95-amp unit?\u003c\/h4\u003e\n\u003cp\u003eWhile the alternator functions through the factory 3-pin plug, installing a supplementary fused 4-gauge power lead directly from the alternator output stud to the battery starter solenoid is highly recommended to safely carry the full 95-amp load without harness resistance heating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Classic British Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to resolve notorious Lucas electrical bottlenecks, this high-output alternator provides period-correct exterior packaging alongside modern electronic reliability, ensuring your classic British roadster runs cooler, charges stronger, and maintains rock-solid ignition voltage.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898720354552,"sku":"DS-E02USZYTR","price":236.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-mg-mgb-midget-1974-1979-1-3l-1-5l-1-8l-1.jpg?v=1793325859","url":"https:\/\/performancechiptuning.com\/products\/high-output-alternator-for-mg-mgb-midget-1974-1979-1-3l-1-5l-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
